- TURNING GRADUALLY COOLER AND WETTER LATE SUNDAY INTO EARLY NEXT
WEEK.
- MOSTLY DRY WITH TEMPERATURES NEAR TO SLIGHTLY ABOVE NORMAL
MIDWEEK INTO THE END OF THE WORK WEEK.
DISCUSSION
NEXT 7 DAYS (THROUGH FRIDAY)...
CONDITIONS REMAIN HOT AND MOSTLY DRY TODAY, ALTHOUGH LESS SO THAN
YESTERDAY, AHEAD OF AN APPROACHING TROUGH. AS A RESULT, FIRE
WEATHER CONCERNS REMAIN ELEVATED. AS SURFACE WIND TURN OUT OF THE
EAST LATE TODAY, INCREASING ATMOSPHERIC MOISTURE, THERE IS A LOW
CHANCE (5-20%) FOR SHOWERS AND THUNDERSTORMS NEAR THE DAKOTA
BORDER LATE TODAY INTO EARLY SUNDAY.
THE NEXT BEST CHANCE FOR PRECIPITATION (40-90%) THEN ARRIVES LATE
SUNDAY INTO MONDAY AS THE UPPER LEVEL TROUGH MOVES ACROSS THE
REGION AND PWATS INCREASE TO 170-210% OF NORMAL. WITH THIS, ANY
SHOWER OR THUNDERSTORM WILL BE CAPABLE OF PRODUCING POCKETS OF
HEAVY RAIN, ESPECIALLY OVER THE WEST AND THE NORTH. A FEW STORMS
MAY BE STRONG TO SEVERE SUNDAY AFTERNOON AND EVENING OVER THE
NORTH AND EAST, WITH STRONG WIND GUSTS AS THE MAIN THREAT. THE
ARRIVAL OF THIS TROUGH WILL ALSO ALLOW TEMPERATURES TO COOL, WITH
HIGHS IN THE 70S OVER THE WEST TO 80S OVER THE EAST BY MONDAY.
TUESDAY INTO THE END OF THE WORK WEEK, MODELS NOW FAVOR A MODEST
RIDGE BUILDING IN. THIS WILL KEEP CONDITIONS MOSTLY DRY AND ALLOW
TEMPERATURES NEAR (70S) TO SLIGHTLY ABOVE (80S) NORMAL TO CONTINUE.
